The LT ? 3652 is a complete monolithic step-down bat-
tery charger that operates over a 4.95V to 32V input
voltage range. The LT3652 provides a constant-current/
constant-voltage charge characteristic, with maximum
charge current externally programmable up to 2A. The
charger employs a 3.3V ?oat voltage feedback reference,
so any desired battery ?oat voltage up to 14.4V can be
programmed with a resistor divider.
The LT3652 employs an input voltage regulation loop, which
reduces charge current if the input voltage falls below a
programmed level, set with a resistor divider. When the
LT3652 is powered by a solar panel, the input regulation
loop is used to maintain the panel at peak output power.
The LT3652 can be con?gured to terminate charging
when charge current falls below 1/10 of the programmed
maximum (C/10). Once charging is terminated, the LT3652
enters a low-current (85μA) standby mode. An auto-re-

TYPICAL APPLICATION
charge feature starts a new charging cycle if the battery
voltage falls 2.5% below the programmed ?oat voltage.
The LT3652 also contains a programmable safety timer,
used to terminate charging after a desired time is reached.
This allows top-off charging at currents less than C/10.
